What is the breakup?

Snowfall measurement has always been a problem for meteorologists - all too often snow refuses to cooperate. Unlike the rain, which tends to behave similarly in almost all conditions, wet snow can stick to the sides of the snow breakup, which uses a funnel type. This may cause snowfall to not report when it happens and exaggerated when the frozen clotting later melts. So instead of attracting snow at the catch point, it can actually be bounced by snow. Meanwhile, behind the breakup, in some places wind piles are driven in some places and in others they leave almost bare countries. It works well for occasional winter weather observers, but generally not accurate enough for meteorologists have focused on determining snowfall on a fraction of the thumb. Voigure of gluing and wind is special problems with this type of snow meter. The basin is a depth of over 50 inches (51 or more centimeters) and snow melts in it when the basin is full or snowfall. The reduction then arrivedBurning of water supply equivalent times 10.

However, there is still some subjectivity with this method, especially if the precipitation is mixed snow and rain. Similarly, the snow device is known as a snow pillow susceptible to wind variations. The sensor inside the "pillow" determines how much snow sits at the top.

Another type of snow gauge has been developed in the last few years by the National Meteorological Service, which Tested it Mount Washington in New Hampshire, at the International Airport and Denver locations in Ames, Ia and Worthington, MN. It consists of two boards, one pointing up and lowering below. They are isolated apart and the difference in the energy required to heat the upper plate compared to the bottom plate provides raw data for snowfall determination.
